Joe, you are of course correct, but I think maybe he said 576 mohms, as
in 576 milliohms, although he didn't type it very clearly. He couldn't
ever have had a VSWR of 1.012 with j576 ohms.

That is *NOT* a resonant frequency - not with -j576 Ohms. Your measured
value at 7.15 MHz (+j7.11 Ohms) is much closer to resonance. I would
estimate the actual resonant frequency ( j0.0 Ohms) to be about 7.13
MHz. Note: *Resonance* is defined as j0 ohms regardless of the real
part of the impedance.
